Fields Using some of the embodiments described herein may not necessarily provide a high intensity spot due to the nature of the system action used during brushing. When a small beam is used while the (4) toothbrush is being brushed, the strength is better but the exposure duration will be lower. For example, a ten-stroke lateral brushing action on a tooth area can expose a point on the tooth at 100 mw/cm2 for a lesser time period than a small time period, while for a larger beam, the intensity can be 25 mw/ Cm2, and the duration of exposure time will be more well understood, there may be several therapeutic effects that may be provided by light and/or heat-enhanced toothbrushes, such as treatment of bad breath (including gingivitis), reduction of bacteria, reduction of dental caries, healing of gums, Enhances the health of the gums and enhances the properties and calcification of the enamel. Each of these phenomena can be further optimized using light from a particular wavelength or wavelength series or band of light sources from the toothbrush. The implementation of the toothbrush can thus be optimized for use individually, simultaneously or in any combination in each or all of the applications.

To the outer region adjacent to the blade 208 (or at the proximal end of the blade 208). In other embodiments, the head 206 can be shaped or configured such that the light source 21 〇 illuminates the surface of the skin that has just been cut using the blade of the bayonet (note that it can be implemented in conjunction with previous windows/holes/openings) For example, use these embodiments). Figures 18, 19 and 20 show various light source implementations of the head in which light 'tubes are used to emit light from between the blades and the proximal end of the blade. Figures i 8 and 9 depict 119524.doc -25- 200800110 including an embodiment of the head 206 of the window 216. Figure 20 depicts an embodiment in which the head 2 〇 6 includes an opening 218 between the blades 208. In such embodiments, one or more light pipes 220 provide a light pipe between the light source 210 inside the razor (eg, in the handle, shaft or head) to a blade adjacent to the head 2q6 Area. These light pipes 220 can comprise optical fibers (i.e., fiber optics), a conduit having a lumen through which light can pass, or a solid light conduit (i.e., a non-hollow lumen). In general, one end of the light guide 22 is placed in the razor such that it is adjacent to the light source and the other end of the light guide is positioned adjacent to the The blade is such that light from the source can pass through the light guide to the (open) "open" end of the blade. In use, the light guide 220 facilitates directing light emitted from the light source to the transfer end such that light from the light source 210 passes from the end of the light guide. emission. In one embodiment, a single light pipe can be used having a single end adjacent to the light source and a multi-fork end adjacent to the blade of the razor to assist in illuminating light at the proximal end of the blade On the desired area. In embodiments where the head 206 of the razor 200 includes one or more windows, the (equal) window may be a window or a translucent window to allow some or all of the light from the source to pass through ( Etc.) Window. This (4) window can also be a frosted window to assist in diffusing light from the source. For example, the inner surface of the window may be roughened or impregnated with a scattering material to provide a scattering transmission similar to Lambertian. 21 and 22 show the percentage of the treatment light source 21〇 located in the head P of the razor. More specifically, FIG. 21 depicts the implementation of the light source (four) in the head of the brake blade, wherein the head has a window 216, and the light source 21 is depicted in FIG. 119 524.doc -26-200800110. The implementation of the crucible is located in the head 206 of the remaining knife 200, wherein an opening 218 is provided between the blades 208 in the head 206. In some cases, light not only provides a beneficial effect on the skin and tissue, but also directly heats the cutting blade to further enhance the cutting effectiveness of the razor. The placement of the (or equivalent) open or free end of the light guide 220 may depend on the pair
